South Australia introduced deregulation in 2013, which means that electricity providers are now free to set their own prices once a year on 1 July. It's hoped that price deregulation can increase competition and put downward pressure on electricity prices.
Most of South Australia's energy (around 60%) is generated through natural gases. However, if you have an eligible solar PV system, you can get access to retailer feed-in tariffs, an initiative that lets you sell unused solar power back to the grid.
There are several rebates and concessions available to Australians living in South Australia, including the following:

Across South Australia, there are two main types of electricity tariffs. These are:
In South Australia, most households are on single rate tariffs, so the price you pay for electricity will stay the same no matter when you use it. South Australia also only has one tariff for all residential households — called "Tariff 110" — but it's used by retailers in different ways. The tariff price you pay is based on "block rates", which means you're charged based on how much you use electricity, not when you use it.
Switching energy providers in South Australia is simple. All you need to do is choose a new retailer and sign up.
